Near Surface Embedded Application for FRCM Strengthening of RC Beams in Flexure
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In this paper, the efficacy of a recent strengthening technique, referred to as Near Surface
Embedded (NSE), has been investigated for flexural strengthening of Reinforced Concrete
(RC) beams using Fabric Reinforced ...
Vibration Prediction Model for Building Developments Adjacent to Railways
(
Qatar Univesrity Press
, 2020 , Conference Paper)
This paper presents the experimental and computational evaluation of ground-borne
noise and vibration impacts at sensitive receivers in the vicinity of existing track
sections. Vibration problems occur as an effect of train ...
Modelling Catchments in Qatar to Assist in Operations
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Qatar is experiencing unprecedented growth and infrastructure is being developed
at a rapid pace. The infrastructure is served by storm water systems which are under
development and need to be resilient in case of storms. ...
Influence of Water Table Fluctuation on Natural Source Zone Depletion in Hydrocarbon Contaminated Subsurface Environments
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Most of the prediction theories regarding dissolution of organic contaminants in the
subsurface systems have been proposed based on the static water conditions and
the influence of water fluctuations on mass removal requires ...
An Innovative Structural Solution to Failed Stabilized Earth Embankment in Multilevel Interchange
(
Qatar Univesrity Press
, 2020 , Conference Paper)
This paper summarizes a case study of a failure in a mechanically stabilized earth
retaining wall ramp heading to a multilevel interchange. The failure was caused by a
washout cavity resulting from a long-term leakage from ...
Predicted and Back-calculated Coefficients of Permeability of Randomly Fractured Rock Mass: A Case Study
(
Qatar Univesrity Press
, 2020 , Conference Paper)
This paper presents the discrepancy between the coefficients of permeability measured
for randomly fractured limestone using field falling-head tests and that back-calculated
for the same rock mass based on the actual ...
Hydrogen Gas Production from the Injection of Nanoscale Zero-Valent Iron and Sodium Borohydride Solutions: Potential Effects Near Injection Wells
(
Qatar Univesrity Press
, 2020 , Conference Paper)
The injection of nano-scale zero-valent iron (nZVI) is a remediation technique for the
treatment of organic and metal contamination in soil and groundwater. The hydrogen gas
(H2) produced during the reaction of nZVI and ...
Numerical Study of Four Bolts End-Plate Joint Behaviour for Robustness Assessment
(
Qatar Univesrity Press
, 2020 , Conference Paper)
The paper presents new studies on numerical modeling (FEM) for beam-to-column
behavior under sagging and hogging bending moment when the framework is exposed to
service and unexpected loads that may cause a column loss ...
Eco-friendly Concrete Using Local Materials From Sudan
(
Qatar Univesrity Press
, 2020 , Conference Paper)
This study is aimed at investigating the potentiality for utilizing some locally available
eco-friendly materials to replace some concrete constituents as a possible opportunity
to introduce sustainable construction in ...
